![]() The previous screens, even though they were being called “2k” screens, were more like 2.5k or 1440p, so around 4MP, while the new screen is actually quite a few pixels more than “4k” at about 10.5MP.ĭepending on which of the previous Mars printers you compare it to, you see more or less of a difference from that in the finished parts – in my experiments, with antialiasing working, the Mars Pro actually had the smoothest surface reproduction, while the Mars and Mars 2 Pro had very visible voxels, which is noticeable even without a crazy macro lens in the way the surface reflects light.įor example, the shield here has a bit more shimmer on those machines and is smoother on the Mars Pro and the Mars 3. The previous machines all had around a 50µm pixel size, the Mars 3 is now down to 35µm. Now, the 4k screen is of course the big feature, but it’s not that life-changing as it first sounds. You still get the quick-release ball head-adjusted bed platform, this time around they’re again using a sandblasted surface, and the only moving in the entire printer part aside from fans, the Z-axis, is super robust and well-built, perfect for the job.įor the actual resin printing hardware, it’s a really nice upgrade over the previous Mars printers as well. I actually saw some of the red plastic starting to rub off. One downside that I noticed is that the lid and base don’t seem to be entirely resistant to either the resin or the ethanol I usually use to clean up around resin printers, and especially on the lid, you can actually see the plastic getting matte where I tried to clean off some of the resin splashes. With the injection-molded base and lid, it’s not really any less sturdy or functional, but it means that they’ll have more budget to spend elsewhere on the machine. ![]() Aside from it feeling very light and therefore pretty cheap, that’s not really a bad thing. It’s fine after a bit of cleanup.īut the Mars 3 is not just a more capable printer, it’s also one that feels like it’s finally been cost-optimized. And of course, the resin didn’t exactly stay in the vat. This one is a lot lighter, so I almost yeeted it across the room. On my machine, you can also see that’s it’s quite messed up already – I managed to slosh resin out of the vat when I tried to turn the Mars 3 around for the camera, but I expected the weight and friction of the earlier Mars machines. It gives you a lot more control over the slicing process, but more on Chitu later. It also comes with a one-year license of the Chitubox Pro slicer, which does a lot of things that the basic, free Chitubox non-Pro can’t do. Just like the upgrades between the previous generations, it’s now again got a slightly larger build envelope, higher resolution on a monochromatic screen, and stronger UV LEDs that allow it to cure layers faster. So today we’re going to check out the Mars 3 and the Mercury X and we’re also going to have a look at the situation around the restrictions that now come with the Chitu ecosystem that Elegoo and basically everyone is using to build their machines. ![]() The Saturn didn’t use to have any matching washing station, and that’s something I find is essential for using a resin printer properly. ![]() But sort of alongside the Mars 3, they also released the Mercury X bundle, which is a set of a cleaning and curing machine that fits the Mars 3 and now finally, also the Saturn. It seems like these machines are basically on an annual release cycle now, where it’s the same as with smartphones – new major release every year, and then a “Pro”, “A” or “C” version in between. So this is Elegoo’s newest resin printer, the Mars 3. But they made their plans without considering the interests of their hardware partner Chitu – and now that everyone is dependent on their parts, they want a bigger slice of the cake. Resin printers are all pretty good these days, so they can work on getting the setups polished and ironing out oversights from previous generations. ![]()
